To all whom t may concern.'

VBe it known that I, EDWARn a citizen of the United States residing atPittsbur legheny and State o Pennsylvania, have invented certain new anduseful Improvements in Adjustable Clamps for Picture- Frames, of whichthe following is a specitcation, reference being had therein to theaccompanying drawing.

This invention relates to an adjustable clamp for picture frames, andthe primary object of my invention is to provide a clamp- H. RINGER, ofAmerica,

ling device that can be easily attached to a frame for retainingpictures, mirrors and panels, together with their backings, in theframe, lirrespective of small differences in the thickness of thepicture and panel, or backing. 1 u Another object' of thisinvention isto provide a frame with longitudinal shiftable clamps'or ,clips that canbe easily sprung into position and as readily released, the use of theclamp obviati'ng the-necessity of injuring the frame by repeatedlydriving fastening means into the frame.

A further object of this invention is to provide resilient clips thatare inexpensive 1 to manufacture and easy to manipulate forthe purposefor which they are intended.

. I attain the above objects by a mechanical construction thatwill behereinafter more specifically described and then claimed. s

Reference will now be had to the drawing,

wherein- Figure l isa perspective view of a por-- tion of the frameprovided with the clamps `or clips; Fig. 2 is a longitudinalsectionalview of a portion of the frame showingone of the clips in a lockedposition, andFig. v3 is a similar view showingthe clip in an unlockedposition. i j

lThe reference numeral l denotesa frame ofthe ordinary and well knowntype, which is chamfered or grooved, as at 2', to receive a picture,panel or :mirror which has vbeen lillustrated by way of an example as atransparent plate 3, having a backing 4, between which there isinterposeda picture 5.

Movably arranged uponA the rear side or the frame l, are a plurality ofresilient h, in the county of Al lclips 6 and a sulicient number ofthese clips are employed to firmly retain the backing 4 within the frame1 and against the picture 5. Theclips 6 are made of light or durableresilient metal bent upon a compound curve with the outer ends thereoflongitudinally slotted, as at 7, to provide clearance for screws 8 orother fastening means employed for retaining the clips in engagementwith the frame. The head 9 of the screw engages the upper surface of theclip, and the curvature of the clip adjacent to the head 9 is suiiicientto hold the cli in two positions. When the clip is pushedp inwardly,thereby placing the outer end of the slot in prox# imity to the screw 8,the inner end of the clip is retained in an elevated osition. To

place the clip in enga-gement with the backl ing 4, it is only necessaryto push outwardly upon the clip. The curvature of the clip causes theinner end thereof to be lowered into engagement with the backing 4, andthe greater effort in pushing the clip outwardly, the greater thepressure brought to bear upon the backing 4 by the clip.

It is obvious that the clip can be easily adjusted and when in anunlocked position it can beA swung in a 4horizontal plane, should it lbenecessary, when placing the picture, panel or backing in position.

What I claim ist The combination with a recessed frame for supporting apicture and badlring, of a plurality of resilient clips, each includingan arcuate vintermediate portion and a pair of curved end port-ions, theend portions being reversely curved with respect to the intermediateportion, each of said outer end portions providedwith a longitudinalslot extending fromthe inner terminus of said outer end portion'to apoint in proximity 'to the outer terminus of said outer endy portion,said inner end portion being imperforate andengaging the.- backing formaintaining it in the frame, and headed screws extending through theslotted end portions and carried by said frame and capable of bearingupon the upper surfaces of the said slotted end portion for returningsaid clips in an adjusted position, the curvature of said clipsinconnection wlth the heads of said screws providing means formainteining the In testimony whereof I aix my signature mner end ortlonsof the chps 1n an ele- 1n the presenoe of two wltnesses.
